+Subject: [PATCH] configure.ac, setup.py: do not add a curses include path from
+ the host
+
+This leads to host contamination, and particularly can cause
+curses modules to fail at runtime if the host curses is configured
+differently to native curses (observed on current OpenSuse Tumbleweed
+as dnf failures).
